I find it deeply offensive that an app could suggest I may not know the word “cornucopia.” I wouldn’t give a shit if it was the only app I could use to pay my bills; if it at any point suggested that I didn’t know a word as common as “cornucopia,” I would delete it immediately, leave a 0 star review, and post the offense to a community like this.

And just to be clear, the bar for how uncommon a word would have to be in order for it not be offensive is way higher than cornu-fucking-copia.

“Terpsichorean.” That’s a word I wouldn’t be offended if they thought I didn’t know it. Or maybe “legerdemain.” I know both of those words, but I wouldn’t be offended if an app assumed I didn’t.
